I have gone through an article of using EntityConnection, EntityCommands for executing Entity sql queries. But I was unable to understand that Why are we using Entity sql? Why not directly using the Classes and objects for processing CRUD operations on database?

Or If we want to execute sql queries then why we are using Entity Sql , why not directly ?

Is there any performance difference or something else?
I have already gone through the page[^]. But I want answer in a more simpler way. Can you please answer me?

The main difference

SQL is database dependent query language working on storage (relational) objects - tables / rows
ESQL is database independent query language working on conceptual (EDMX) objects - entities
ESQL was created prior to LINQ. In some scenarios ESQL offers more functionality than LINQ.
